Mitosis Phases Summary
Mitosis is how cells make copies of themselves. It's like a tiny factory that helps our bodies grow! Here are the main steps of mitosis:
Interphase
- Getting Ready: Before mitosis starts, the cell is busy getting ready.
- Copying DNA: The cell makes a copy of its DNA, which is like a recipe book for making new cells.
Prophase
- First Step: The first phase of mitosis.
- Organizing Chromosomes: The DNA gets organized into something called chromosomes, which look like little Xs.
- Nucleus Disappears: The nucleus (the cell's control center) starts to break down.
Metaphase
- Middle Line: The chromosomes line up in the middle of the cell, like kids lining up at school.
- Spindle Fibers: Tiny strings called spindle fibers attach to the chromosomes to help them move.
Anaphase
- Sure Bye-Bye!: The chromosomes get pulled apart and move to opposite sides of the cell, like a tug-of-war!
- Getting Ready to Split: The cell is getting ready to separate into two.
Telophase
- Almost Done: The last phase of mitosis.
- New Nuclei Form: Two new nuclei form around the separated chromosomes, like a new home for each set of DNA.
- Cell Getting Ready to Split: The cell starts to look like it’s going to split in two.
Cytokinesis
- Last Step: This is the final step after mitosis is done.
- Splitting the Cell: The cell actually splits into two new cells, each with their own nucleus and DNA.
- Now We Have Two!: Yay! Now there are two cells instead of one!
